Right, the Performance Update 2.0 (the one that bumps Gen 5 CX to
120Nm/750W with up to 600% rider support) is famously coy about showing up. There's a well-trodden checklist for coaxing it out:
1. Update the Flow app first
The performance update requires a recent Flow app version. Annoyingly, on iOS the app often won't tell you an update is available from within the app itself — go to the App Store directly, search "Bosch Flow", and hit Update there.
@SIG84 flagged this exact gotcha

2. Install the regular eBike update first
The 120Nm performance update is a
separate step that only appears
after you've installed the standard software update. As
@FlashToBang explained, you have to scroll to the bottom of the eBike update screen in Settings, where a second "Performance Update" option lurks

3. Force-close and reconnect
If you've done both of the above and it still won't show, force-close the Flow app entirely, reopen, and reconnect to the bike.

4. Nuclear option: uninstall and reinstall
Several riders had to uninstall the Flow app completely, reinstall, pair the bike again, and only then did the performance update appear. Tedious but reliable.
5. Check your bike actually qualifies
Performance Update 2.0 is for
Bosch Performance Line CX Gen 5 (Smart System) and the CX-R only. Gen 4 CX (most 2023-ish bikes) doesn't qualify — it stays at 85Nm/540W (though it did get eMTB+ mode in the autumn 2025 update). On a Mondraker Crafty R 2025,
@AlsbachRyder confirmed the path is
Components > Drive Unit > Performance Update 2.0 → view post.
The 2026 Bullit ships with a Gen 5 CX so you do qualify. The most common reason it doesn't show is one of the prerequisites above — Flow app not on latest, or standard eBike software update not fully installed yet (the 2.0 option only appears once that's done).
One known quirk: a few riders report getting the bump partially — wattage goes up but the torque slider doesn't move. The uninstall/reinstall procedure above is the documented fix.
What phone OS are you on, and have you got the Flow app on its latest version?
(Edit: corrected the torque figure — Performance Update 2.0 is the May 2026 update that bumps Gen 5 CX to 120Nm/750W. I'd originally written 100Nm, which was the May 2025 update.)
